GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 754,651, dated March 15, 1904.

Application filed April 12, 1902. Serial No. 102,554. (No model.)

To all whom, it may concern:

. wall of the passage F and the burner D. The

Be it known that I, HENRY A. GUIGNON, a citizen of the United States, residing at Corry, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Gas-Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to gas-stoves; and it consists in certain improvements in the construction thereof, as will be hereinafter fully described, and pointed out 'in the claims.

The invention is illustrated in the accompanying drawings, as follows:

Figure 1 shows a front elevation. Fig. 2 shows a section on the line 2 2 in Fig. 1. Fig. 3 shows a section on the line 3 3 in Fig. 2. Fig. 4 shows a section on the line 4 4 in Fig. 2.

The gas is admitted through the pipe A into the mixer B, of the usual form, and is conducted by the pipe C to the burner D. The burner D has the jet-openings d, which are arranged to invert the flame. The burner is of annular shape. The flame is directed against the fireback E, which is coated with some substance, as asbestos, for becoming incandescent under the heat of the gas-flame. Surrounding the mixer-pipe C is a central draftpassage F. This extends through the base I, and its outer opening is provided with a regulator f, by which the size of the opening may be regulated. The upper end of the draft-passage F is inclosed by the burner D, so that the passage fis formed between the burner is preferably provided with the shoulder cl to make the passage F of uniform width. The fireback and burner are inclosed by a case Gr, having the transparent opening g therein. The case is provided at the top with the draft-opening g, and the register or regulator-plate g is arranged to entirely close the draft-opening g or regulate the size of the opening. Heated gases pass from the fireback through the opening H directly into the front portion of the base I, up the fiues J to the top K, down the flues L into the rear por- 5 tion of the base I, and out the exit-pipe M.

as the draft becomes sufficient the regulator g is moved, uncovering the opening 9. The

proper adjustment of draft may be accomplished by the regulators f and 9'. Proper equalization can be readily discerned by the action of 'the flame on the fireback E. The central draft passes up through the fireback and is deflected, so that it does not flare the flame at the fireback. The openings H are arranged within the diameter of the fireback E, so that the outer draft tends to force the flame against the fireback E, thus insuring an incandescent effect on the fireback. The heated gases direct from the flame pass first into the front part of the base, so that the base is one of the hottest parts of the stove. The arrangement of burner and fireback may be used so that the flame has an upward direction; but I prefer the inverted construction shown.

What I claim as new is 1. In a gas-stove the combination of a burner arranged to invert the flame; a fireback; walls forming draft-passages at ,both sides of the flame; and a regulator on one of said passages for balancing said passages.

2. In a gas-stove the combination of an annular burner arranged to invert the flame; a supply-pipe leading from the bottom of said burner; and a fireback surrounding an airpassage, said supply-pipe being surrounded by said air-passage.

3. In a gas-stove the combination of an inverted burner having a downwardly-extend-' ing annular lip; and a fireback extending into said burner, said fireback having adraft-passage arranged within it adapted to deliver air between the lip and the fireback.

4. In a gas-stove the combination of a burner having a downwardly-extending annular lip; a fireback extending into said lip and forming a passage between it and the lip said fireback having an air-passage extending through it to said passage between the fireback and the lip;

walls forming an exit-passage at the bottom of the fireback; and walls having a draft-opening arranged to deliver air outside of the flame.

5. In a gas-stove the combination of the nular burner; front base I, to which the heated burner D, having a downwardly-extending angases pass direct from the burner; the flues J nularlip; a fireback E, extending into said leading from the base I; the top K, into which burner and inclosing the airpassageF;'areguthe fiues J lead; flues L, leading from the top I5 5 later f, for said air-passage; an outer case G K, to the rear base I; and an exit-pipe G.

having an opening 7, in the top thereof; a Intestimony WhereofIaffiX my signature in regulator for said opening; walls forming an presence of two witnesses.

exit-passage H, of smaller diameter than the HENRY A. GUIGNON. fireback E; and the base 1, into which said Witnesses: IO exit-passage leads. 0. R. POWELL,
